Last summer I picked up a tandem on craigslist. The good news is that my SO enjoys riding it with me, and that it fits reasonably well. The good news in respect to the tandem is that it only cost me $150, plus changes I've made, mostly with parts I had around. The not so good news is that it's a 1976 LeJeune.
I've replaced the 650B wheels with 700c wheels with DT TD hubs, Hed (of course) C2 rims (32 hole), and brakes to accommodate the rim change.
The rear derailler was replaced by the previous owner and is now a mid line Shimano MTB derailler. It's shifting the 9sp cassette I put on the back just fine via bar con shifters I installed.
Not as good:
I'm assuming that the bottom bracket is French or Swiss threaded but seeing as it's reasonably smooth right now I don't feel the need to take it apart and find out. I'm not entirely sure what I'll do when the stoker BB wears out as I don't want to spend the $$ on a Phil BB.
The part that is concerning me more than the BB however is the TA Cyclotouriste cranks. Both the timing rings and triple crank are in good condition at the moment but, it seems that there aren't a lot of rings for that crank about anymore. At the same time, it seems that nobody wants them, so it isn't worth pulling them now to keep them in their currently good condition. Does anybody have any advice on the cranks other than ride them until they die and then replace them?
The front brakes (Linear pull) squeal a ton. No amount of toe in, rim cleaning, or pad changing (currently Kool Stop black) seems to fix the issue. I have tried machined aluminum rims as well as ceramic coated Mavic rims.
The headset (1" threaded) is on its way out, although I have the tools to change that.
The seat tubes appear to be ovalized rather than round from over tightening. Both chromed steel (1") seatposts show slight pinch marks from being overtightened as well. Despite this obvious over tightening, they still slip. The stoker seat doesn't slip much, but the captain's seat rotates when the stoker pushes harder on one side of the handlebars than the other. If anything makes it difficult to control a bike, it's the seat rotating because it makes it feel like the frame is tilting when it isn't.
Any suggestions on these issues will be appreciated.
Unrelated: Seeing as I'm always doing stuff to recumbents, I've decided to try to make an independent coasting setup for the tandem. I'm want to put it in an EBB as the stoker BB is fixed. Easton EBBs look much cheaper than Bushnell, but do they work? Similar to Easton;
